Draw the MO diagram for `O_2^+` This is a bit of a curveball, but a perfectly valid problem. Recall that a cation indicates a loss of `1` electron. `O_2^+` is just the ionized form of `O_2`; that is, it's `O_2` with `1` missing electron. The MO diagram will be the same as the MO diagram of `O_2`, except with `1` less electron. The electron analysers are constructed from molybdenum and are mounted from two rotating gear plates controlled externally via the rotation feedthroughs on the top flange (see figure 2). The analysers are mounted onto x-z translation tables that allow them to view the interaction region accurately over the full range of angles accessible. Drupal-Biblio 17 ...

Positron emission. Electron capture. Alpha emission. An alpha particle is defined as a positively charged particle of a helium nuclei. An alpha particle is composed of two protons and two neutrons, so it can be represented as a Helium-4 atom.
Electron emission from metal Thermionic emission Electric field electron emission Photoelectric emission The process of electron emission is somewhat similar to the ionization process.
Aug 28, 2008 · Field emission cathodes fabricated using thin‐film techniques and electron beam microlithography are described, together with effects obtained by varying the fabrication parameters. The emission originates from the tip of molybdenum cones that are about 1.5 μm tall with a tip radius around 500 Å.

Surface analysis - Surface analysis - X-ray photoelectron spectroscopy and Auger electron spectroscopy: For XPS and AES the primary process is an ionization caused by either a photon or an electron, m + hν → m+* + e−, or m + e− → m+*+ 2e−, where m is an atom in the material. In photoionization an incident photon causes the ejection of an electron with a discrete kinetic energy ...

Diamonds have excellent electron emission properties, yet their performances are limited by the requirement for thick films and the defects within. We address these challenges by creating electron emitters from monolayers of diamondoid molecules and demonstrate electron emission with small energy dispersion, low operation voltage and high ...

Insightful Reviews for electron emission
Field emission SEMs are designed for high resolution imaging. Key to the performance of a field emission SEM is its electron optical column. Gemini is tailored for excellent resolution on any sample, especially at low accelerating voltages, for complete and efficient detection, and ease-of-use.
Link ETH Grants with publications and research data. In addition to SNSF and EU grants, ETH-internal grants can now also be entered as funding information for a publication in the submission form of the Research Collection.

Carbon was coated on the surface of molybdenum grids by ion beam assisted deposition. The electron emission characteristics from the grids with and without carbon, which were contaminated by an active electron emission substance of the cathode, was measured using an analogous diode method. The results show that electron emission from the carbon-coated Mo grid was much less than that from the ...
The field emission cathodes turn on at bias voltages as low as 25 V, and their gates transmit almost 100% of the electrons to the anode. The cathodes produce per-emitter electron currents in excess of 2 µA (current density >2 A/cm2) at a bias voltage of 80 V. A desktop rig is built to generate X-ray with a field emission cathode and ...
This type of emission uses a high electric field produced by a gate electrode to increase the probability of electron tunneling. High electric fields at relatively low gate voltages are achieved by concentrating the field around nanowire tip emission sites.
